This 5-position USB Motorized Filter Wheel is the only commercially available motorized filter wheel for 50mm diameter filters that is compatible with Thorlabs’ wide range of SM2 (2.035″-40) thread and 60mm cage optomechanical components. Based on a high-performance DC gear motor, when used with USB control this wheel runs entirely from the USB supply and consumes less than 100mA. The wheel is also capable of operation from a serial input which requires a battery or other power supply. The wheel is quiet in operation and the Hall-Effect 3 bit encoded positioning gives absolute filter locations (not serially sequential) so you can easily swap between any filters without accidentally losing the wheel position. Includes 3 m USB cable and software.

Wheel accepts up to five 50mm round filters (unthreaded), up to 5mm thick
